As British rabbis, it is with great regret that we find it necessary to write, yet antisemitism within sections of the Labour party has become so severe and widespread that we must speak out with one Jewish voice.

The Labour party’s leadership has chosen to ignore those who understand antisemitism the best, the Jewish community. By claiming to know what’s good for our community, the Labour party’s leadership have chosen to act in the most insulting and arrogant way.

It is not the Labour party’s place to rewrite a definition of antisemitism accepted by the Crown Prosecution Service, College of Policing, the Scottish parliament, the Welsh assembly, the National Union of Students, and 124 local authorities, including scores of Labour-held councils, including Haringey and Greater Manchester – but above all else, accepted by the vast majority of Jewish people in Britain and globally.
